The bill amends the Michigan election law by making several key changes to the procedures for calling special elections and filling vacancies in the state legislature. Notably, it mandates that the governor "shall" call a special election within 30 days of a vacancy occurring in the office of a state senator or representative, replacing the previous language that allowed the governor to decide whether to do so. Additionally, the bill specifies that if a vacancy occurs after the primary election but before the next general election, the governor "shall" direct that the vacancy be filled at that general election, ensuring a more timely response to legislative vacancies.

Further amendments include the requirement that special elections must be held on regular election dates, with specific provisions for school districts to call special elections under certain conditions. The language throughout the bill has been updated to replace terms like "may" with "shall" to impose stricter obligations on the governor and other officials regarding election procedures. The bill also clarifies the process for candidate selection by political parties in the event of a vacancy and establishes guidelines for petition requirements for school district elections. Overall, these changes aim to streamline the election process and ensure that vacancies in the legislature are addressed promptly.
